Hexamethylethane

Explanation:

(H3C)3CC(CH3)3. The parent hydrocarbon contains 2 quaternary carbon centres (which cannot be halogenated because it has no hydrogens to substitute), and 6 methyl centres, all of which are equivalent.

Substitution of any methyl centre gives an identical product.

(H3C)3CC(CH3)3+X2(H3C)3CC(CH3)2CH2X+HX

How would you name this beast systematically?
